Monday (January 21) was a historic day for several reasons: the second inauguration of President Barack Obama as the 44th president of the United States, as well as Martin Luther King, Jr. Day. But perhaps one of the most talked-about events from the day was the jaw-dropping entrance Beyoncé and Jay-Z made when they took the stage at the inauguration.

Before her stunning performance of the "Star-Spangled Banner" (after which she planted a kiss on the POTUS), Bey walked to the stage with her hubby in a stunning in a long black gown and emerald earrings, her long, wavy hair in a striking blonde. Even Rep. Pete King just had to snap a picture of the two as they walked.

Hip-hop's power couple are longtime supporters of the president, hosting fundraisers throughout the 2012 campaign. Beyoncé also gave a historically beautiful performance of "At Last" at an Inaugural Ball four years ago.

During her rendition of the "Star-Spangled Banner" today, Beyoncé thrilled the live crowd in D.C. and the televised audience with spirited vocals that seemed to grow even more moving when the multiplatinum R&B singer tossed her in-ear monitor aside electing to and sing with no musical aid.
